Holographic interferometry in conjunction with fiber optics is specially useful for the measurements of a small area deformation, a micromovement, or an intracavity deformation. A single-mode imaging fiber bundle can give higher resolution, better coherency, and less sensitivity if it is used as an image guide system in holographic interferometry. Time-average hologram and stroboscopic double-exposure hologram of a vibrating surface with acceptable signal to noise ratio is presented.
